- Empty bobbins produced in the fine spinning frame are automatically conveyed from the fine spinning frame to a standby rail by the magazine driving mechanism. Thereby, the operator's labor can be saved.
- the removal of residual yarns can be automatically effected, thereby making it possible to increase the operating efficiency and automate the operation of removing empty bobbins from the magazine.
- full roving bobbins produced by a fine spinning frame are automatically conveyed to a position below a magazine positioning mechanism by a conveyor, each full roving bobbin being positioned by being separated from the following ones by a bobbin positioning mechanism, and they are successively mounted in magazines by a multi-axis robot; thus, conveyance of full roving bobbins from a flyer frame and the operation of mounting them in magazines can be automated, achieving labor saving.
- full roving bobbins produced by a flyer frame are placed on a conveyor automatically or manually by an operator and conveyed to the position of a lifter, where an operator manually places them on the lifter, whereupon the lifter lifts a plurality of full roving bobbins and mounts them in a single magazine at the same time.
- the operator's labor can be saved.

- the main body 105 has mounted thereon traveling wheels 106 adapted to contact the lower surfaces of the rails F and D, reversible motors 107 for driving said traveling wheels 106, batteries 108 serving as power sources, a radio receiver 109, and a control device for controlling the reverse motors 107 by the radio receiver 109.
- the power source for the automatic conveying tow vehicle M may be in the form of a system comprising a trolley line and a current collecting member. In that case, the trolley line is laid along the rails.
- the front portion of the main body 105 is provided with a hook 111 adapted to be releasably engaged with the support rod 11 which is part of a magazine.
- This automatic conveying tow vehicle can also be installed on the second connection rail F.
- the arrangement of the residual yarn removing means N will now be described.
- the residual yarn removing means N is used to remove residual yarns from the empty bobbins in the magazine I row conveyed from a fine spinning frame rail C, said residual yarn removing means being installed somewhere in the standby rail E, as shown.
- the concrete arrangement as shown in Figs.
- the lifting suction nozzles 115 are longer in length than residual yarn bobbins 13b and connected at their upper ends to a lifting body 116 adapted to be lifted and lowered along a lifting guide 117 with respect to a suction chamber 112 and fixed suction sleeves 113.
- the fixed suction sleeve 113 has a seal packing 118 installed around the periphery the of the upper end thereof to prevent suction air from leaking from between it and the lifting suction nozzle 115. Further, a thin annular blade orifice 119 is installed in the lower region of the inner surface of the fixed suction sleeve 113 to produce a turbulent action by its choking effect, thereby increasing the sucking action on the residual yarn.
- the communicating portion 120 between the lower end of the fixed suction sleeve 113 and the suction chamber 112 forms a communicating hole smaller than the inner diameter of the fixed suction sleeve 113.
- the suction chamber 112 is connected at its lower end to a suitable dust collector (not shown) and fixedly supported at its four corners by pillars.
- said residual yarn removing device N including said fixed suction sleeves 113 and lifting suction nozzles 115 is a magazine positioning mechanism R for moving magazines by one pitch each time.
- This magazine positioning mechanism R is the same as the one previously described.
- the removal of residual yarns is effected by lifting the lifting suction nozzles 115 by the lifting means 14 and inserting them into residual yarn bobbins suspended from the magazine I, whereby the residual yarns are extracted in a few seconds by being sucked downward.
